OEM PV Series Dry Variable Pitch Screw Vacuum Pump from Vacuum Pump Manufacturer
1. Product Overview
The AIRIPA PV Series Dry Variable Pitch Screw Vacuum Pump is an industrial oil-free vacuum pumping solution featuring an equal-diameter, variable-pitch screw rotor design. Its dry pumping chamber helps prevent oil contamination of process gases, while the variable-pitch structure is designed to improve internal gas compression and pumping efficiency.
The series includes 12 models, with nominal pumping speeds from 80 to 2,500 m³/h, rated motor powers from 3 to 55 kW, and a specified ultimate pressure of ≤1 Pa.
Combining water cooling, variable-frequency drive control, nitrogen purge protection and an integrated enclosure, the PV Series is designed for demanding industrial vacuum applications, including semiconductor-related equipment, vacuum coating and advanced manufacturing.
2. Key Features & Benefits
Equal Diameter Variable Pitch Rotors
The variable-pitch screw design provides progressive gas compression, helping improve pumping efficiency and manage energy consumption.
Oil-Free Pumping Chamber
Dry, non-contacting screw rotors operate without oil inside the pumping chamber, reducing the risk of process gas contamination.
High Vacuum Performance
The series has a specified ultimate pressure of ≤1 Pa, supporting industrial processes requiring a clean vacuum environment.
Variable Frequency Drive
Variable-speed control allows pumping operation to be adjusted to different process requirements, subject to the selected configuration.
Water-Cooled Operation
An integrated water-cooling system helps control operating temperatures and supports stable performance during industrial use.
Nitrogen Purge Protection
Dedicated nitrogen purge and sealing provisions help protect internal components in suitable process environments.
Low Leakage Design
The specified leakage rate of 1 × 10⁻⁶ Pa·m³/s supports applications where vacuum system tightness is important.
Integrated Pump Enclosure
The enclosed unit design combines pumping equipment and supporting systems to simplify installation and maintenance access.
3. Working Principle
The PV Series uses two synchronized, non-contacting screw rotors with an equal-diameter, variable-pitch geometry. As the rotors turn, gas enters the inlet, moves through progressively changing chambers and is compressed toward the exhaust.
The pumping chamber operates without oil injection. Water cooling manages operating temperatures, while variable-frequency drive control adjusts motor operation according to process requirements. Nitrogen purge and sealing systems provide additional protection for compatible industrial gases.
